INTRODUCTION
1.- INTRODUCTION
ARK-70 series offers the user a perfect tool for processing, with four processor models
available with two or four inputs and eight outputs (analog or digital and Ethersound system optional).
ARK-70 series processors offer Double Dynamic, with a RMS compressor/limiter and PEAK
limiter. RMS limiter is used to adjust the sound level of the transducer, keeping the original dynamics
while respecting the original transition, getting a better acoustic result. Peak limiter controls the
maximum movement of the speaker, and protecting against damage while reducing the distortion
caused by an over-excursion. This Double Dynamics minimizes distortion levels and provides
protection for all acoustic and electronic components of the system.
With fixed latency of 0.6 ms ARK processors offer one of the lower latencies on the market. All
ARK models offer 120 dB dynamic range and AD-DA converter Cirrus Logic high-performance 24-bit
and 96 KHz. The internal DSP processor works with double precision floating point, reaching a 56-bit
internal resolution, one of the highest resolutions available today on the market. This allows the use of
high-precision filters with very low distortion and providing a quality and unsurpassed sound clarity.
ARK-70 processors offer an atmospheric compensation function, essential when working
outdoors, where temperature and humidity can vary considerably between day and night causing a
major loss at high frequencies, especially over long distances. Each output can be configured
separately depending on the throw required for each box.
In the security section, different levels of access restrictions are included. That can be
managed by a global password and a preset password, with the choice to select which processing
functions can be modified or not. The front panel can also be blocked, denying any access.
For the available ARK control software, we recommend reading the software manual. The
control software for ARK processor is designed to provide the user with a fast and intuitive access to
each process area, facilitating the programming of the processor from a computer. The software
manual is a document available in the downloads section of the web site www.vmb.es

FUNCTIONAL DESCRIPTION
3.- FUNCTIONAL DESCRIPTION
ARK-70 Process diagram.
Four floating point DSPs (Digital Signal Processors) with 56 bits of internal resolution are included
in the ARK processor. All this calculating power is used in the signal processing algorithms which control
all the process: input delays, global equalisation, crossover filters, individual equalisation for each way,
output delays, protections and dynamic control and independent noise gate per output. All of these
algorithms have been developed to provide the best precision and the lowest round-off noise in the
calculations. This way, the best sound fidelity and transparency free of noise is achieved. The wide internal
range (56 bit) allows the use of high-precision filters with very low distortion. Cirrus Logic converters 24-bit
and 120 dB dynamic range assures a clean sound without distortion and background noise makes the ARK70 one of the processors in the market with the best technical characteristics.
Once the analog input signal is converted into a digital one, the processing inside the ARK DSPs
is as follows:

sensitivity in each way.
29 Band
GEQ/PEQ
GEQ/PEQ: ARK-70 offers for each input a 29-band graphic equalizer with two choices of Q, the
classical and a special algorithm, which adapts the Q in terms of how are the other filters, to get
a smoother response and more optimal acoustics. For ARK-70 family it is also possible to switch
the equalizer in PEQ mode, so that we will have 29 fully configurable parametric filters.

FUNCTIONAL DESCRIPTION
DELAY
PEQ
DELAY: Configurable delay. In the inputs A-B up to 211 msec. for covering a distance up to 73 m.
For the inputs C-D up to 54 msec, for covering a distance up to 18 m It is mainly useful
when working with important PA equipment covering a large distance with reinforcement blocs
quite far from the stage. It allows 20 msec at outputs, which correspond to 7 meters approximately.
Thanks to that function, it is possible to rectify the cabinet’s position (alignment) in a multi-way
equipment and avoid cancelling problems due to phase cancellation effects.
PEQ: Output equalisation. There are 9 filters completely configurable per output. These filters
can be parametric, 6dB/oct. and 12dB/oct. low frequencies Shelving (with or without Q), 6dB/oct.
and 12dB/oct. high frequency Shelving (with or without Q), 12 dB/oct. highpass and lowpass,
bandpass, reject band and first and second order Allpass filters. Its aim is to provide a final
equalisation on each way of the equipment.

AIR ABSORPTION COMPENSATION: Apply the compensation curves necessary to restore the
levels of the frequencies absorbed by the air with distance. These vary with temperature, humidity
and distance, following the laws of physics. An indispensable tool for live events.
CROSSOVER: Bands separating filters. Different filters are available: Linkwitz-Riley, Butterworth
and Bessel up to 48 dB/oct. It is also possible to put them in By-pass without affecting the
corresponding way to have full bandwith output.
DYNAMIC: Dynamic section. The ARK-70 offers a sophisticated RMS compressor-limiter, plus a
peak limiter on each output. Limiters and compressors are C.R.I. type (Continuous Increment
Ratio) for low distortion.
First using a RMS detector for a high-quality compression. The system will reach its
maximum power gradually and the sound is perfectly crisp and clear at all times, avoiding the
usual problems of normal limiters. Then we have the peak limiter which can control the maximum
mechanical displacement in speakers. Also available is a noise gate that will respond with the
same timing as the RMS dynamics and you can select different thresholds of noise to remove.
On the ARK frontal can see when a way is limiting because LIMIT LED lights. We also
have a second LED + L, which lights up when we have exceeded a certain amount of compression.
This over-limitation value may be set by the user to the desired level from the global configuration
of the processor.

OPERATING INSTRUCTIONS
4.- OPERATING INSTRUCTIONS.
How to proceed.a.- Before switching on the processor:
ARK includes a precise switching power supply. That means that it can adapt itself to any input
supply voltage from 84 and 264 volts and frequencies from 50 to 400 Hz. This is the reason why the processor
is guaranteed to work perfectly under any voltage and the final sound quality is completely independent of
the supply voltage or the kind of generator used. Nevertheless it is recommended to check the supply
voltage before working to avoid any possible problem when connecting at 380 volts. A fuse holder is included
in the ARK processor with a spare fuse (1 A) situated in the IEC connector input of the power supply
connector.
It is recommended to turn off the volume of all the power amplifiers down to 0 before switching on
the processor. We will then be able to check whether any of the 4 processor outputs are connected to their
corresponding power cabinets, avoiding any irretrievable damage in the loudspeakers (specially in
expensive high frequencies drivers).
In any installation, it is suitable to place audio and lighting systems in independent power lines to
protect both parts separately and to avoid interferences between the different equipments.
b.– Once the processor is ON:
When switching on the ARK processor, audio outputs remain short-circuited to ground for a few
seconds in order to avoid the dangerous start up transient time necessary for the processor to receive a
stable voltage and to check internal functions such as: good running of the converters, working memory
checking, DSP processors start-up and current configuration loading. Subsequently, if everything is
correct, all the outputs will commutate at the same time introducing audio in each output with a soft-start
(The audio will be increased until reaching the value set in the preset).
Display, buttons and encoders.ARK processors come, for programming all functions, with 24 characters and two lines LCD display,
as well as a series of navigation buttons and encoders for real-time modification of various parameters.
Despite being able to modify any parameter, it is recommended to use the ARK software for better
viewing of EQ curves and ease of programming.
DESCRIPTION OF THE MUTE/EDIT BUTTONS:
Using these buttons can mute either input A, B, C or D, as well as outputs 1-8. Inputs or outputs muted
will be red illuminated continuously. In the case that we have entered into the edit menu, these push buttons
will help us to select the input or output for editing. The input or output editing will blink in red.

ENCODERS DESCRIPTION:
The encoders provide us with a direct access to different parameters that can be modified. Depending
on the menu where we are, these encoders will have different parameters asociated.
Encoder 1 Encoder 2 Encoder 3
In the silk-screen printing of the frontal you can see associations, helping the user and facilitating
programming.
- If we are in the equalisation menus, the encoder 1 will change the frequency of the current filter, the
encoder 2 the Q and the encoder 3 the gain.
- If we are in the crossover, the encoder 1 will change the cutoff frequency, the encoder 2 the slope
or filter order (-6, -12, -24, -48 dB) and the encoder 3 type filter.
- If we are in the dynamics, the encoder 1 change threshold limiting, the encoder 2 compression ratio
and encoder 3 knee of the compressor / limiter.
- For the gains the encoder 1 has no association, the encoder 2 will amend the polarity and encoder
3 the gain.
- And the delay, the encoder 1 has no association, the encoder 2 will change the global temperature
and encoder 3 the own delay.

will access the next screen, in which we can modify the dynamic threshold with
encoder 1 for the selected output. The range is from +18 dBu to -50 dBu. With encoder 2 will control
the compression ratio, that will go from 1:1 (no compression) to 1:10 (for each 10 dB upper the threshold,
the output takes 1dB). With encoder 3 we can change the limiter knee. For the limiter case, the
compression ratio will not be displayed, because it is equivalent to a ratio 1: infinity. With Up and Down
Keys we change dynamic type: compressor or limiter.

Pushing
we can access the next window. Then we can use the encoder 3 and modify
the Noise gate level in the selected input. This level is from -79dBu to -37dBu, or switch off (bypass). This
value will be the noise threshold to be deleted. For example, if we adjust to -79dBu then the gate could
delete noise from -80dBu to down, and when the noise level will surpass -79dBu then the gate will be
opened. The oppening and closing times are fixed by the Dynamic RMS attack and release times of this
output.

TROUBLESHOOTING
6.- TROUBLESHOOTING
In this section we try to give solutions to possible problems:
1 – The processor does not start up:
Check the power supply cord. If it is correctly connected and the red led on the front panel does
not light on, check the fuse situated in the input of the power cord.
2 – The processor starts up but there is no sound:
Check that the processor is being provided with a signal in the correct input, A, B, C or D. If the
signal does reach the processor, the green signal LED will light.
3 – The resulting sound is “strange”:
Check that the 4 outputs and their corresponding cabinets are correctly linked. Always be careful
in increasing little by little the cabinets volume channel by channel in order to check the correct connection
and not to damage the transducers.
4 – One of the cabinets ( with the same signal ) sounds less than the others:
Check that the joining cable from the processor to the cabinet is well balanced otherwise the
output signal will fall 6 dB.
5 – Audio sounds wrong and distorted.
Verify that we are not saturating the input (beyond the 19 dBu input). In this case the LEDs
light up red clip. Sufficient to reduce the input signal to the processor, until no clip LEDs light up. If
this does not work, verify that the signal is not distorted out from the previous gear, for example the
mixer, which could be the gain of that channel very high and saturating the mixer input.
6 – Buttons or encoder do not work.
Verify if there is any keyboard lock activated from the software.
7 – I can not connect by Ethernet.
Check that the USB cable is not connected,it has priority and internally disables the Ethernet
connection. If this is not the case read Annex Ethernet in the software manual.
